Patented @et l, 1929 LEO J. ONEIL AND LEO B. BECKER, OF NEW' ORLEANS, LOUISIANA GAS Mrxna Application led March 23, 1928. Serial No. 264,884.

This invention. pertains to devices for mixing gas and air, and more particularly to de-` vices of this character which are adapted to be installed in the conduits or pipes which convey the gas to a stove or burner.

Gas, such as that which is commonly used for heating and lighting purposes, is composed of approximately sixty-five per cent gas units and thirty-five per cent air. In flowing through a conduit as between a gas meter and a burner, the gas, being lighter than the air, will separate therefrom and flow through the upper portion of the conduit, the air flowing through the lower portion thereof. This results in a very poor flame and a great waste of gas.

An important object of the invention is to provide, in a manner as hereinafter set forth, a device of the aforementioned character which may be quickly inserted in a gas pipe by simply disconnecting one of the joints or couplings therein and when so inserted, will thoroughly mix and atomize the air and gas passing therethrough.

Another object of the invention is to provide a device of this character which is simple in construction, Iefficient in its use, and which may be manufactured at low cost.

'Other objects and advantages of the device 3o will be apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like reference characters designate corresponding parts throughout the several views.

In the drawings Figure 1 is an elevation of a gas stove and a fuel supply pipe therefor. showing the adaptation therewith of a mixer in accordance with this invention. y Figure 2 is a longitudinal section showing the device installed in a gas pipe, a portion of which is shown in section. 4

Figure 3 is an elevation of the device'. Figure 4 is a front elevation of the wire mesh disc which is placed in one end of the device, and

Figure 5 is a rear elevation of the'wire mesh disc which is placed in the opposite end of the mixer.

The reference character 1 designates a con- Aend thereof. The inwardly turned iiange 8 constitutes an atomizing nozzle, the pur -pose of which will be hereinafter more fully' set forth. 'The flared portion 7 isof a'size tov fit snugly within the pipe*` 3. The tube 6 lis provided, at arpoint near its opposite ends,

with ribs 9,' lsaid ribs forming annular grooves or recesses 10 in the inner walls of the ltube, for a purpose whichwill be presently set forth.

.vent-ional gas meter having a conduit, com- A baille, comprising a spirally twisted strip 11 havingintegral ears 12 on its opposite ends,`

is positioned within the tube 6 intermediate l" the grooves 10. The strip 11 is of a' length corresponding to the distance between the grooves 10. A pair of meshed wire discs 13 and 14, having openings 15 for the passage of the ears 12, are secured upon the opposite ends of the strip 11.` The disc 13 is of coarser mesh than the disc 14. The peripheral edges of the discs 13 and 14 are adapted to seat in the annular grooves 10 and serve to hold the strip 11 in its proper position within the tube. l

Our device is used in the following manner.

A section of the gas pipe, preferably one near the burner or stove, such as 3, is disconnected from vthe rest of the pipe 2 by means of the coupling 4. The tube 6, having positioned therein the strip 11 and discs 13 and 14, is passed into the pipe, the peripheral edge of the flange portion 7 of said tube frictionally engaging the inner wallsof the pipe for the purpose of holding the tube in posi-v tion therein and to prevent the passage of any of the gas and air between the tube and pipe. The sections of pipe are then joined again by the coupling 4.

Gas and air, passing through the pipe, will enter the flared end of the tube 6 and pass through the coarser meshed wire disc 13 and be partially broken up and atomized. The'air and gas are then thoroughly mixed by the spirally twisted strip 1l, after which same is further atomized by passing through the line meshed Wire disc 14. The mixture then passes through the nozzle formed by flange 8 and is further mixed and atomized. The gas and air then How to the burner 5 Where a much hotter ame may now be had due to the more complete' burning olfthefuel as a result ofbeing thoroughly mixed.

Itis thought that the many advantages of a mixer Constnucted in accordance with this inf vention will be readily understood, and although the preferred embodiment of the'.

Vention is as illustrated and described, it is to be understood that -e'lianges i-ri the details l of construction may be made which Will fall Within the `scope of the appended cla-im. l

What is claimed is: Y

A dev-ice of the character described comf prising a tube having spaced annular 'grooves positioned inwardly ifro'I-iV the 1 ends thereof,

ai spiral mixing baie positioned inlsadtube intermediate the grooves, fora-minous atni'iiing discs of diferent-mesh securedfto -tlie opposite ends of the baffle, the peripheral edges and constituting means for seouringtlie bae Y therebetween, an atomizing nozzle one end of the tube and means formed on the other' 'end of the tube for -secur'in ame in position? .in a pipe line.

In `testimony whereofgwe affix our signatures hereto.
